SPECIFICATION forming part of Letters Patent No. 429,343, dated June 3, 1890. I

Application filed January 31, 1890. serial No. 338,707- (No model.)

To all whom it may concern.-

Be it known that I, HORATIO GALE, a citizen of the United States, residing at Albion, county of Calhoun, State of Michigan, have invented a certain new and useful Improvement in Cultivators and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specificaion.

In the drawings, Figure 1 is a side elevation of my cultivator. Fig. 2 is a rear elevation of the same. Fig. 8 is a plan View. Figs. 4, 5, 6, and 7 are details of the construction.

My invention relates to that class of cultivators known as walking-oultivators; and it consists of the several improvements hereinafter described and claimed.

In carrying out my invention, A represents the tongue, and B the wheels.

O is a transverse horizontally-arranged bar, which constitutes a part of the axle and is rigidly engaged to the tongue A. The upright members or rods D D constitute the balance of the axle, each upright member or rod D being bent at right angles to itself and provided with a sleeve D on its upper end, while the wheel is journaled on the other end. These sleeves embrace the bar 0, and the wheels thus support the tongue.

E are the beams, preferably of piping, and each one engaged to the axle by the swivelfitting F F, so that each beam has not only a vertical movement, but a free horizontal movement.

G are the handles engaged to the rear ends of the beams.

H are the cross-beams, to which the teeth I are directly engaged. These cross-beams are passed underneath the beams E, and are engaged thereto by the blocks H and bolts h. The upper sides of the beams H, adjacent to where the beams E cross, are slightly concave, and the under face of the block H is made concave, so as to properly fit the surface of the beam E and clamp the cross-beam H to it. The object of this construction is to adjust the tooth-carrying cross-bars H from a horizontal plane to different angles relatively to lower the other end of the tooth-carrying bars,

and in the oscillations of the latter to adjust their angle of inclination relatively to the ground the caps H and bolts 12. turn or'move with such bars. J is what may be termed the doubletree or evener, and is pivoted to the tongue A. To this doubletree the sin gletrees J are attached, and extending from the doubletree back to the axle are the rods K, whereby the, doubletree is rigidly connected with the members or rods D of the arched axle. Thus a preponder ance of draft on one side acts to pull that entire side forward and to throw the other'side correspondingly back.

L are spiral springs engaged to the double tree and extending down to and engaged in the loops Z, which are in turn engaged with.

the beams E. These springs act by their tension to regulate the depth at which the teeth travel, and by providing the rack-bar L at the upper end the tension of the springs may be regulated as desired. By providing the notches or depressions Z in the loops l the lower end of the spring may be adjusted laterally, and thus change the point of tension on the beams E, so as to make them work toward or from each other, as desired. So, also, by providing the arms M either. set of teeth may be lifted up and its corresponding beam E engaged over the hooks an.

\Vhat I claim is 1. In a walking-cultivator, the combination, with the tongue, the arched doubletree pivoted thereto, the arched axle engage with the tongue, and the beams engaged with t e axle and connected with the doubletree, of the tooth-carrying cross-bars adapted to oscillate on the beams in a vertical plane to vary their angle of inclination relatively to the ground and means for holding the said bars in their adjusted position, substantially as described.

2. In a Walking-eultivator, the combination, with the tongue, the arched doubletrce pivoted thereto, the arched axle engaged with the tongue, and the beams engaged with the axle and connected with the doubletree, 0f the tooth-carryin g cross-bars adapted to oscillate in a vertical plane on the beams to vary their angle of inclination relatively to the ground, the elamp-bloel s on the beams, and the bolts connecting the clamp-blocks, and the bars for holding the latterin their adjusted position, substantially as described.

3. In a walking-cultivator, the combination, with a Wheel-axle and the beams having a swivel-connection with the axle, of the toothcarrying cross-bars adapted to oscillate in a vertical plane on the beams to vary their angle of: inclination relatively to the ground and devices for holding the bars in their adjusted position, substantially as described.

4:. The combination,'in a cultivator, with a tongue, an evener thereon, an axle connected with the tongue and evener, and the side beams having the swivel-fittings connecting them with the axle, of the loops Z, engaging the swivel-fittings and having their upper ends provided with notches or depressions Z, and the springs L, connected to the evener and engaging the notches or depressions of the loops, substantially as described.

In testimony whereof I sign this specifieation in the presence of two witnesses.
